Java Training Courses

Course Description:
Java has established itself as a language for application development for server side computing, but with a reputation as being too large and slow for real-time embedded software.

This course shows how Java can be used in real-time and embedded projects and importantly provides developers with significant advantages over other languages. A complete tour of the Java facilities for the resource-constrained environment is provided, including J2ME in depth, Java Card and the Real-Time Java Specification.

Overview:
This five day course provides a thorough grounding in the Java language, highlighting the significant benefits the language provides real-time developers in terms of portability, concurrency, productivity and reliability.

Via a mixture of demonstration and practical sessions, delegates will gain a sound appreciation of which resource constrained environments Java is applicable in and importantly those for which it is not. Forty percent of the course is based on practical work.

Course Objectives:
• To provide an understanding of the fundamentals of the Java programming language
• To introduce concurrency and networking aspects of Java
• To provide a complete picture of the Java landscape for resource constrained environments
• To introduce and provide experience of writing Java for different application domains (e.g. J2ME and Java Card)
• To highlight how Java can be used on embedded hardware

Delegates will learn:
• The core Java syntax and semantics
• How to use Java in embedded and consumer devices
• To evaluate if Java is an appropriate language for a project
• To write concurrent and networked solutions
• How to write code for J2ME in particular MIDlets for MIDP
• About memory and performance issues associated with Java

Pre-requisites:
It is expected that delegates will have experience in programming in a high level language.

Who Should Attend:
The course is suitable for anybody who wishes to gain a thorough understanding of the Java programming language and its use in resource-constrained environments, particular J2ME.

Duration:
Five days.

Course Materials:
• Delegate Handbook

Related courses:
• OO-503 Real-Time Software Design with UML 2.0
• RTOS-201 Fundamentals of Real-Time Operating Systems
• EL-503 Developing for Embedded Linux
• EL-504 Developing Linux Device Drivers

Course Workshop:
The course exercises are based on a case study of a remote monitoring
and control system. This includes building (all in Java):
• A configuration utility as a graphical user interface
• A full concurrent Web server
• Mobile phone access using with a J2ME MIDP MIDlet.
• Smart card identification.

This case study highlights a complete end to end system implemented in Java and highlights the advantages and disadvantages of the language as well as providing practical experience of the important Java application domains.
